How to Delete Elements from a DOMDocument in PHP Without Creating a New Document?

Deleting Elements from DOMDocument

It's often necessary to manipulate the content of HTML documents loaded with DOMDocument. One common task is to remove elements from the DOM.

Consider the following code:

<code class="php">$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($html);

foreach($dom->getElementsByTagName('a') as $href)
    if($href->nodeValue == 'First')
        //delete</code>
Copy after login

How can the First element be removed from the DOM without creating a new document?

Solution

To remove a node, instruct the parent node to remove the child:

<code class="php">$href->parentNode->removeChild($href);</code>
Copy after login

Refer to the $parentNodeDocs property of DOMNode and removeChild()Docs method for further details.
